Abstract
The subject of the invention is a ball joint for motor vehicles comprising a bearing insert (4) located between a joint housing (1) and a ball head (3). The bearing insert is provided with meridionally extending slots (9) arranged in a half-portion gripping of the ball head over the equator. A clamping ring (5) located in the housing grips the tongues (10) of this bearing insert (4). To improve the elasticity of the bearing parts while retaining a good distribution of lubricant, the clamping ring (5) is provided with circumferential grooves (13) on its inner surface and with openings (15) in the outer end surface (14).
